SPECIFICATION forming part Of Letters Patent No. 725,959, dated April 21, 1903.

Application filed June 21,1902. Serial No. 112,666. (No model.)

To all whom, it may concern: shaft hereinafter referred toin the claims, is

Beitknown that we,JAMEs SAMUEL HEATH, a gear or pinion 3, which receives motion in aBritishsubject,andERNEST BAsEMAN,a citithe manner now to be described from the zen of the United States,both residing at Maceaxle 4, which is the driving-shaft hereinafter 5 don, in the county of Wayne and State of New referred to in the claims. The gear 6 is fast 55 York, have invented certain new and useful upon the axle 4 and is contained within the Improvements in Speed Mechanisms, of which case or frame 5, which is pivotally mounted the following is a specification. upon the axle and contains also a gear 7,.

As the case 5 moves about the axle 4 as a center the outer portion of the case 5 will move in the arc of a circle, and we have therefore formed the end 11 of the strap or link 10 in the arc of a circle having its center in the axle 4, so as to insure its constant proximity to the case. The case 5 is provided on its outer edge with a lug 17, which is inwardly recessed, so as to receive therein the cylindrical portion of the rotatable sleeve or thimble 18. The thimble 18 is provided with a pair of projectinglugs or shoulders 19 19 and is longitudinally bored, as shown in dotted lines in Fig. 5, for the reception of the locking-bolt 20. The bolt 20 is formed at one end with a recessed head or loop 21, which passes over and engages the end 11 of the strap 10, the head or loop 21 being so shaped that when the bolt is moved longitudinally it will pass between the lugs or shoulders 10 19 of the thimble 18 and press the end 11 of the strap 10 against the said shoulders and lock the strap 10, thimble 18, and bolt 20 firmly together. At the other side of the lug 17 the bolt 20 is provided with a transverse piece or pin 22, between which and the thimble 18 the head of the locking-arm 12 is interposed. The head of the arm 12 is formed with a pair of oppositely-placed cam-surfaces 23 23 to engage the pin 22 upon the bolt 20 in such manner that when the arm 12 is turned in the direction of the arrow in Fig. 6 the action of the cam-surfaces 23 23 upon the pin 22 will draw the bolt 20 through the thimble 18, thereby locking the end 11 of the strap 10, the bolt 20, and the thimble 18 firmly together.

The devices just described constitute a convenient means of connecting the case 5 to the strap 10 at any desired point to compensate for the different diameters of the changegears 8 employed, and the thimble 18 being rotatably mounted in the lug 17 and locked securely to the strap 10 affords the proper amount of play when the strap 10 is moved so that the case 5 may be shifted to disengage the gear 8 from the gear 3 without bind or friction in the connecting parts.

It is obvious that many changes and variations may be made in the mechanisms described and that the principle may be applied to other uses without departing from the spirit of our invention.

Having thus described our invention, its construction and mode of operation, what we claim, and desire to secure by Letters Patent of the United States, is as follows:

1. Inaspeed mechanism,adriven shaft and a gear thereon, combined with a driving-shaft and a gear thereon, a case or frame pivotally mounted onthe driving-shaft, a single second gear contained therein and engaging with the gear on the driving-shaft, means attached to the said gear whereby a change-gear may be directly connected thereto, and a change-gear mounted thereon and meshing directly into the gear on the driven shaft, the said changegear being one of a series of change-gears having different diameters, together with shifting means for the case and means for changing theposition of the case with reference to the shifting means.

2. In aspeed mechanism, adriven shaft and a gear thereon,combined with a driving-shaft, a case pivotally mounted thereon, a gear on the driving-shaft located within the case, a single second gear supported within the case and meshing into the gear on the drivingshaft, a stud attached to the second gear, and a change-gear mounted on such stud and meshing directly into the gear on the driven shaft, the said change-gearbeing one of a series of change-gears having different diameters, together with shifting means for the case and means for changing the position of the case with reference to the shifting means.

3. In aspeed mechanism, a driven shaft and a gear thereon combined with a driving-shaft, a change-gear supported thereon and actuated thereby and arranged to mesh into the gear on the driven shaft, together with means to disengage the change-gear therefrom, and means for changing the position of the changegear with reference to the disengaging means.

4.. In aspeed mechanism, adriven shaft and a gear thereon,combined with a driving-shaft, a case or frame pivotally mounted thereon, a change-gear carried by the case or frame and actuated by the driving-shaft and arranged to mesh with the gear on the driven shaft, a disengaging strap, and means for adjustably connecting the case or frame to the strap.

5. In a speed mechanism, the combination of a pivotally-arranged gear-case and a train of gearing, a portion of which gearing including a change-gear is mounted in the gearcase, with a disengaging strap and means for adj ustably connecting the strap to the case to allow for the different diameters of the change-gears employed.

6. In a speed mechanism, the combination of a pivotally-arranged gear-case and a train of gearing, a portion of which gearing including a change-gear is mounted in the gearcase, with a disengaging strap formed in the arc of a circle and means for adj ustably connecting the strap to the case to allow for the different diameters of the change-gears employed.

7. In a speed mechanism, the combination of a pivotally-arranged gear-case and a train of gearing, a portion of which gearing including a change-gear is mounted in the gear-case, with a disengaging strap, a rotatable piece connected to the gear-case, and means for adjustably connecting the disengaging strap with the rotatable piece to allow for the different diameters of the change-gears employed.

8. In a speed mechanism, the combination of a pivotaily-arranged gear-case and a train of gearing, a portion of which gearing is mounted in the gear-case, with a disengaging strap, a rotatable thimble connected to the case, a bolt connected to the strap, and means to rigidly connect the thimble, bolt and strap.

9. In a speed mechanism, the combination of a pivotally-arranged gear-case and a train of gearing, a portion of which gearing is mounted in the gear-case, with a disengaging strap, a thimble formed with projecting lugs and rotatably mounted upon the case, a bolt provided with a head to embrace the strap and passing through the thimble, and suitable means whereby the bolt may be moved longitudinally to draw its head within the lugs of the thimble and to bind the strap thereto.

10. In a speed mechanism, the combination of a pivotally-arranged gear-case and a train JAMES SAMUEL HEATH. ERNEST BASEMAN.
